Layer-by-layer process (LbL), One of molecular self-assembly method, has been widely studied in many fields because it has relatively easy and simple process steps in room temperature and normal pressure. Also, Self-assembled multilayer films by using LbL process can be controlled their structural, chemical characteristics as changing polyelectrolyte sets, the number of LbL steps, and many other conditions on LbL process. Polyelectrolyte multilayer films (PEM) have been applied in many engineering parts; one of the parts is synthesis of metal nanoparticles on PEM. According to synthesized metal nanoparticles, they have largely studied as biosensor, biocompatible materials, and catalysts and so on. In many various metal, we synthesized Pt and Pd nanoparticles which are generally used as catalysts on PEM that were made of Poly allyamine hydrochloride(PAH) and Polyacrylic acid(PAA) by LbL process. Then, we analyzed them for properties to use UV-Vis. Spectroscopy and TEM. |
